How are those spaghetti-thin connecting rods going to react to a dose of "go fast" ????? You're going to need about $2K worth of H-beam connecting rods and forged pistons. The crankshaft should be strong enough to handle the load, but the pistons and rods don't have a chance. I'm using a set of 6 1/2" long H beam rods in a stroker engine I'm building on a 261 block.
